I'd like to point out that if you are adopting unaltered ferrets from a
shelter, they aren't a shelter, they are a breeder, and you aren't adopting
a shelter ferret, you are purchasing a kit.  Ethical shelters will not
adopt out an intact ferret, even if they were not the breeder of this
animal.  Ethical breeders will alter their retired breeders before placing
them, and will not refer to their retired breeders as shelter ferrets.
This practice is all to common, and disgusts ethical shelter operators.
 
That said, shelters have the right to adopt or refuse anyone they want on
any grounds they choose.  It sounds like you are dealing with a breeder,
not a shelter.  You might want to check the SOS list for a list of shelters
in your area.
